Role of industrial engineering department in apparel industry:

Importance of industrial engineering (IE) tools that can be used to improve upon the productivity and thus enhance the profits. Very few companies have been operating with a full fledged industrial engineering department and even those which boast of as an industrial engineering department(IED) are not allowing freedom and scope to function to its full capabilities. The role of IED is important for the garments industry for the following two

reasons:It’s highly labor –intensive industry. Effective planning is emerging as one of the key factors for the garments manufacturing industry.

Work Study

Method Study Work Measurement

What is work study?

Work study is mainly concerned with the examination of human work.

There are two parts of work study:

• To eliminate wastage of time and labor.• To reduce fatigue and boredom of work by avoiding

unnecessary movements.• To find a best way of doing a job.• To have more utilization of materials, machines and

workers.• To improve the design of work place layout.• To train the individual operator in its practice as per

standardized methods.

Why work study?Southeast University

9

• Set target• Manpower allocation• Calculate efficiency• Production planning and

control• Determine cost

Why Work Measurement is Important?

Method study:

The main purpose of method study is to

eliminate the unnecessary operations and to achieve the best method of performing the operation.

Southeast University

11

Time Study:

To determine the time it should take for a qualified worker to perform a specific task using a specified method by directly observing an operator.

In this case, we need to follow PDCA process improvement chart which can give us a solution.

PDCA

Figure : The Shewhart Cycle is a fundamental idea for continuous process improvement.

Quality:Quality means customer satisfaction

17

Benefits of TQM: The benefits of TQM can be classified into the following two categories:1. Customer satisfaction oriented benefits.2. Economic improvements oriented benefits. 

1. Customer satisfaction oriented benefits: The benefits under this category are listed below:(a) Improvement in product quality.(b) Improvement in product design.(c) Improvement in production flow.

 2. Economic improvements oriented benefits: The benefits under this category are as follows: (a) Reductions in operating costs.(b) Reductions in operating losses.(c) Reductions in field service costs.(d) Reductions in liability exposure.

Time Study Exercise

Process Name = Side Seam

Observed Time = 35.27 SecObserved Rating = 92%Allowance = 25%

Basic Time = (35.27 X 0.92) Sec= 32.45 Sec

SMV = 32.45 + (32.45 X 0.25) Sec= 40.56 Sec

Capacity = (3600 ÷ 40.56) Pcs/ Hour= 88 Pcs/ Hour

Product enhancements Design innovations

Standardizing design Investing in training and the development of employees.

Investing in better plant and equipment.

Management – WorkerImproving the planning or work

Improving methods of production Effective worker selection process

Some Suggestion

20

Ways of improving productivity

– improving worker effectiveness– Providing workers with

adequate training– Improving morale– Rewarding success– Improving attendance levels– Reducing labour turnover– Effective communications– Measuring the performance.

Conclusion WITH THE APPLICATION OF WORK STUDY CHARTS IN APPAREL MANUFACTURING, THE EFFECTIVE UTILIZATION OF RESOURCES ( MAN, MATERIAL & MACHINES) CAN BE ACHIEVED.

THE COST INVOLVED IN USING THESE CHARTS ARE VERY MINIMUM AND A SOLUTION CAN BE DERIVED IN A SHORT PERIOD OF TIME.
